SPEEDER.

SPECIFICATION forming part of Letters Patent No. 272,216, dated February 13, 1883.

Application filed August 31, 1882. (No model.)

To all whom it may concern:

Be it known that I, ALBERT A. DAVIS, of Lowell, county ofMiddleseX, State of Massachusetts, have invented an Improvement in Speeders,of which thefollowing description, in connection with the accompanying drawings, is a specification. y

This invention relates to that class of Inachines knoovn as speeders, and is an improve-ment on the United States Patent- No. 228,809, June 15,1880,to which reference may be had. In the apparatus described in that patent the bobbin slides up and down on the quill, and is rotated by means ot' a hook or prong carried by the spindle, which prong extends out through a longitudinal slit in the quill and engages a radial notch within the head of the bobbin, the engagement of the said hook or prong and bobbin during the descent ot' the latter and the spindle depending upon the weight of the bobbin and that of' the yarn load thereon. In practice, when the bob bin has but little yarn upon it, it has been found that the bobbin, by reason of its friction against the quill friction, increased by rapid centrifugal action, fails to descend properly,

-andthe hook or prong becomes disengaged from the notch inthe bobbin, When the latter ceases to be rotated. To avoid this difficulty I have provided a bobbin-receiving sleeve, which Ihaveintroduced between the metallic quill on which the spindle hasheretof'ore slid andthe interior of the bobbin. The bobbin tits this sleeve, and the latter is engaged by the hook or prong of the spindle, and is moved up and down on the quill by the spindle, so that the inner surfaceot' the bobbin is not subjected to sliding friction and does not touch the quill. g l

Figure l represents in side elevation a suficientportion of a speedeI-frame to illustrate my Invention; Fig. 2, an enlarged sectional detail of parts of the bobbin,sleeve, quill, and spindle 5 Fig. 3, a section of the bobbin, sleeve, quill, and hooked or pronged part of thc spindle, on the dotted line a', looking upward; and Fig. 4 is a detail showing in side elevation the lower end of the sleeve.

The spindle a, having the hook or prong'b, the slotted quill o, bobbin d, and means torrotate the spindle, are substan tiallyas in the patent referred to, so need not be herein further describedf The bobbin is rotated by means of the hook or prong b, which enters one of the notches, 2, in its head.

In this my invention I provide the bobbinreceiving sleeve e-a stiff and rigid sleeve, preferably of thin metal-which I place upon the quill, and I then place the bobbin upon the sleeve, the bobbin having, if desired, a more or less adhesive tit thereon. The sleeve, at one side, nearits lowerend, is provided with a short slot,f, through which is extendedthe hook or prong b, so that the said sleeveis moved up and 'down in unison with the spindle,.andis compelled to follow the spindle as the latter descends. Thebobbin is placed upon this sleeve, and the hook or prong b, in engagement with the slot f and notch 2, rotates the sleeve vand bobbin. In this way the interior ot' the bobbin in its reciprocation is not subjected to friction upon the quill, as heretofore, and the hook or prong b and bobbin-head cannot become disengaged during the winding of the yarn thereon. The Iller g and the presser IL are and may beas usual in speeder-frames. The upper end of the quill is held in place by the sliding rod c2, having a pin, 3, by which to move it.

I elaim- The flier, hooked spindle, and quill, combined'with the bobbin-receiving sleeve e, provided with a slot or opening to be engaged and moved upon the quill by the hook ot' the spindle, whereby the bobbin is relieved from frictional contact with the quill, substantially ALBERT A. DAVIS.
